Ok then a month ago we were selling at cost to try to keep our customers, we were still more expensive than the big Shell site down the road, most people look for the cheapest fuel, so obviously, we didn't sell much for a few weeks, so that cost us. this has happened on more than a few occasions, many we are only making 1-2p a ltr to try and keep somewhere near the station down the road.
As we do not have large storage tanks the cost to us is on the spot so fluctuates a lot more, not unlike the supermarkets and big multi-owned sites that buy in advance millions of liters at a cheaper rate.
But you cannot keep everyone happy
